ភាសាខ្មែរFlanges on the market today are all manufactured according to certain standards, such as JIS, BS, ANSI, DIN, EN, etc. These standards will set out general technical regulations for convenience. production and installation. In this article, Bao Tin Steel will introduce everything about the most popular types of flange standards today.
Flange standards include technical specifications on thickness, inside and outside diameter, hole center, number of holes, distance between holes, and hole size of separate flanges or industrial valve flanges. The standards organization issues this standard to ensure the product’s suitability for various scenarios.
JIS flange standards: 5K, 10K, 16K, and 20K
One of the most prestigious and commonly used Asian standards around the world today is the Japanese standard JIS.
JIS standard is the abbreviation for Japan Industrial Standard (JIS). This is a set of specific standards and guidelines used in Japanese industrial activities. JIS flange standards are divided into many types: JIS 5K, JIS 10K flange standards, JIS 16K, JIS 20K,…
Currently, the JIS standard is not only used in Japan but also receives high praise from experts and is recognized for use worldwide with the highest quality equipment.
JIS standard flange sizes range from DN10 to DN1500, with a variety of materials such as steel, stainless steel, cast iron, plastic, etc. a variety of flange types to meet many practical applications.
